I think Lobo swallowed a rock! The rock somehow managed to get into the treat bag. I was giving treats to Riley and Lobo and threw the rock away. Lobo and Riley went searching for it I'm pretty sure Lobo swallowed the rock. I told the owner instantly and she thinks Lobo is going to be fine. A rock that size won't hurt him. I'm pretty anxious and paranoid something is going to happen to him like die.
